352
Description Memory Validation Failed – Blockware Data Structures
Possible Cause A hardware memory failure because application process data was modified (data should not change after
controller goes online)
Solution Replace the controller.
353
Description Memory Validation Failed – Configuration Shared Memory
Possible Cause A hardware memory failure because system process data was modified (data should not change after
controller goes online)
Solution Replace the controller.

Description Memory Validation Failed – IONet Data Structures
Possible Cause There is a hardware memory failure because IONet process data was modified (data should not change
after the controller goes online)
Solution Replace the controller.
355
Description State Exchange Voter disagreement detected
Possible Cause
• State Exchange disagreement found
• Application sequencing error
• IONet malfunction or hardware problem
Solution
• Use the ToolboxST disagreement display (View | Disagreements) to determine which variables are in disagreement.
• In the application, avoid use of global variable 'ControllerID' and avoid the use of 'USB_HB' block.
• Check IONet (switches, cables). If problem persists, replace the processor module.

Description NANs detected in CALC or NAN_BREAKER block
Possible Cause
• NaN (Invalid floating point number) received from I/O interface
• Hardware problem
Solution
• Check for external devices that may be sending NaNs to the controller.
